By praying outside saloons, throwing rocks in saloon windows, and destroying saloons with her hatchet, _____. A. prohibiting alcohol by Carrie NationB. alcohol was prohibited by Carrie NationC. Carrie Nations work for the prohibition of alcoholD. Carrie Nation worked to prohibit alcohol

Note: I am bad with prepositions, so I was having hard time picking the better answer out of C. and D. Why is C. incorrect? (Because Carrie Nations is misspelled or the verb “work” missed either “-ed” or “-s”?) I guess my question is: are both Sentence1 and Sentence2 correct? “ Carrie Nation worked for a cause.” --- Sentence1“ Carrie Nation worked for the prohibition of alcohol.” --- Sentence2
